WATER-METER.

To all (t /win it may concern lie it known that I, JAMEs M. BUn'roN, a citizen ofthe' United States, residlng m long Island City, county. of Queens, in the State of New York, have invented certain new and useful Improvements in Water- Mcters, of which the following is a specification,-reference being had to the accompanying drawings, which form a. part hereof.

In Letters Patent of the United States No. 1,001,578, dated August 22, 1911, there is hown and described a water meter in which the ordinary or low-duty flow is metered and in which an extraordinary or high-duty How is permitted without obstruction or substantial reduction'of head, such high-duty flow takingplace when water is required in unusually large quantities for fire purposes. ln,an application for Letters Patent filed by the present applicant December 15, 1911, Serial No. 665,924, there is shown and described a meter of the samegeneral characteiqas that shown and described in said Letters Patent, but in which the-re is provided not only a metering device for low-duty flow but a proportional metering device for highduty flow at one side of the path of straight flow, the high-duty passage and the low duty passage being controlled by valves, the one of which closes as theother opens, and

vice. versa.

The present invention relates to' meters of the character of that shown in said Letters Patent and in said application and especially to meters of the particular character shown in said application, in which both passages are controlled by valves.

The objects of this invention are to secure a very quick closing-of the low-duty valve when the high-duty valve opens and in fact a closing oflthe low-duty valve as the highduty valve starts to open and before it does actually open. so that the accumulated prgs sure behind the high-duty valve throws it open very quickly; and to provide for a temporary relief of pressure through the low duty passage as the high-duty valve is closing, so that there shall be a partial equalization of pressure whereby the high-' duty valve is permitted to make its final closing movement very qulckly. The general purpose, of course, is to prevent loss of accuracy in metering at the time of changing from one fiow to the othe The invention will be more: fully explained Serial No. 779,661.

hereinafter with reference to theacompariying drawings in which it is illustrated and in which- 1 Figure l is a top view, section, of a. meter :whic vent-ion. Fig. 2 is a view on the irregular plane indicated b the broken line 2+2 of Fig.- 1, looking 1n the direction" of the arrows, some parts being mly inihorizontal shown in elevation.

The metering devices may be of any suitable character, the 'liigh duty metering device a. being an inferential metering device, with "its turbine wheels or ordinary construction,

The low-duty mete-ring device an is preferably positive, and is shown conventionally as located at one side of and above the path of the high-duty How and as connected in the usual manner to a lowduty register of ordinary construction, the

location of which is indicated at a. As will be understood, during a period of highduty flow a small proportion of the total flow passes through the high-duty metering device a and serves to register inferentially or by proportion the total flow while during a period of low-duty service t e entire flow .20 Ti er 80 ante oi v curedto shaft h,

or upon the Geneva gear is, is provided at one end with a fin er gear 70, for movement o'f the 11: and a notch lo", and at the other end i as pivoted thereto a link k which is slotted as at It. On the shaft 0 of the double butterfly valve e is secured at Geneva gear A which cooperates 1n the usual manner with a mutilated or Geneva gear 2" which is suitably' pivoted adjacent to the shaft e 'i Mounted upon the some pivot so as to move with the Geneva gear Z, is e three-armed plate Z having an arm 1 an arm Z with a projecting beveled lug ll. and. an arm Z pro vided with a pin Z which enters the slot is in the link The cam term it carries, on an adjustable plate h it pin of. The arm h is also provided with e pin it" and the end of the arm is extended to form a toe h.

The operation of the highduly valve f has already been described. I 1 In describing the operation of the lowam v: valves it will be assumed, first that the parts are in the position shown in Fig. 2, with the higlnduty valve f closed, the lowduly butterfly valve c in open position and the low-duty butterfly valve c in closed position, the entire flow under the low-duty conditions then. passing through the lowand through the by the valve e. If it be assumed now that the pressure differential increases greatly so that the valve f begins to open, the pin h of the lever k engages the notch in of the arm k and effects nearly a quarter turn oftlie butterfly valve 0 thus substantially shutting off the flow through the low-duty metering device. before the valve 7" has actually opened. thereby increasing momentarily the differ ential of pressure which tendsto open the valve f, so that the continued movement of the valve f is very quick. In the continued Ol'Klllllg movement of the valves f the pin 7:, of the lever 71 strikes the arm Z and throws it from the position shown in Figs.

2 and i to the position shown in Fig. 3. It will be understood that While in Fig. 2 the which they occupy when the valve f closed and the valve 1 is open, they are shown in Fi 4 in the positions wlic'i they occupy W en the valve c has been closed and'the valve has commenced to open, the arm 2 still be ing in the position which it occn ies when the valve e is open, as shown in ig. 2. It will. further be noted that during the movement of the valve 'e already described, the slotted link It slides (in the pin Z, by reason of the provision of the slot if, so that the. arm Z not moved by the movement of the arm k and thgvalveb'i In this position,

" oosen however, the pin 2 stands in the left handend of the slot 70", as shown in Fig. 4, so that whemthearm Z is moved of the arm 74, the pin Z travels freely in the slot k and if it strikes the right hand end of the slot is (referring to Fig. l), the .efiect is merely to throw the arm 73 a little farther overand close completely the valve 6 if the valve did not move, inits first move- Qmenlato a completely closed position. The movement of the arm Z produces a corresponding movement of the Geneva gear Z and, a corresponding movement of the Geneva stop Z, thereby effecting a quarter turn of the double butterfly valve uh The purpose of this movement is merely to set the-parts'in position for subsequent action.

" The movement of the valve 6 at this time takes. place during the change. from low pressure to high pressure and although there is a temporary opening of passage through the low-duty meter, such serves no special purpose. The valve 0 having been closed and the valve 0 having received a quarter turn, the arm. I). and the arm 9 with the valve 7 continue their movement to the extreme open position and the high-duty flow continues through the now wide open port a without interruption and without substantial loss of head so long as the high pressure differential continues, a 101l3l0li of the flow passing through the high-duty metering device a and causing the proper re istration by the registering devices at a When the pressure difierential falls to normal or low-duty degree the valve f swings downward and the weight if, acting through the shaft it and arm 72 presses the valve) to closed position. It is desirable that the low-duty valve/c shall not be opened until the valve f has closed enough to stop completely the flow of water through the port a but it is also desirable that there shall be a partial equalization of pressure on the opposite sides of the valve during the last part of its closing movement in.

order that such closing movement may be completed quickly. This partial equalization of pressure is accomplished by opening temporarily the passage through the lowduty devices. This is accomplished in the following manner, it being assumed now that the arm it is moving from the position which it occupies when the valve f is wide open to the position which it occupies when the valve is closed. In this movement the portion of the arm it near the pin 71. strikes the lug Z on the arm Z of the three-armed lever -Z and through the described connections gives the valve 6 a quarter turn, the pin Z traveling freely in the slot 76 of the linkjc This quarter turn of. the valve aifords it temporary release of pressure the low-duty passages, and although pening.

by'the pin Z 1 i l l the valvc'c from its closed position shown in Fig. 3 and indicated in Fig. 4., to its open position llhlli'tllell in .l ig. 2, the slotted link sliding freely over thepin l", but insurary opening of the passage.-

As the movement 01" the arm-it log the completion of the movement of the valve to its inilial position thrmigh con- (art of the left hand end of the slot 7U" (reicrring to Fig. :l) with the pin Z 7'' being now completely closed and the butterfly valve 1: being open, the low-duty tlow (:onlinues and is accurately measured by tlic-low-duly metering devices a", it

Although certain specific devices .t'or eftectingthe closing of the low-duty passage before the high-duty open, at the time of a change from a low pressure differential to a high pressure lif-' terentiah and for pr 1 ducing a partial equalization of the pressure on the high- (luty valve during its final closing move ment and l permanently opened have vbeen described herein, it will he understood that various mechanical lltl'lCiS i lll accomplishing these resulls may be constructed and that the invention is not limited to the particular constructnn v shown and described herein.
